Hey guys, I lowered my f150 about 7 months ago, i had a 4 degree pinion shim and the U-Joints(NEW)still clanked when i accelerated. Installed my 6 degree shims and made a worlds difference. What possibly could be damaged that i should take a look at, besides the U-joints ( no more clanking, so might not be damaged) considering i ran it 7 months like that. Thanks Guys
